mac mail corrupt

I have a friend here at work who has started to get all her copy in her mail coming through as none descript jibberish consisting of numbers, and what appear to be math symbols. This is happening when she tries to type too, which as you can imagine is a complete nuisance.

I am wondering if anyone has had anything similar and if so how was it solved.

It appears to be some kind of minor bug.

We have repaired permissions and reinstalled macOSX.

The system we are running is:

OS 10.4.10
Intel Core 2 Duo

Any help will be greatly appreciated.

You'd probably want to post what type of mail server Mail is connecting to, and whether you've tried getting it in another program or through a web interface or that kind of thing. What you're describing almost sounds like attachments that aren't encoded right or are being corrupted or something.

Sorry I shouldn't have said the 'copy' is corrupt. It's all the text, it starts in the email headers, then after time using mail eventually ends up in the main copy of the other emails. After a computer restart it's fine for an hour or two.

It's a POP3 mail server, the same server as the rest of us are connecting to. No web interface, just all through Mail.

I'm assuming it's something that may have come from a damaged attachment, or from some junk she may have opened or something. I have no idea.

Have done that and the program still seems to be doing it. I'm thinking whether the problem is inside each email file as the problem is still there.

Have deleted the mail preferences and have reset the computer but the problem is still there. What does seem to keep it away for a while is repairing permissions, but it still insists on coming back.
